OddOrEven is a simple math's tutor to teach your child the difference between odd and even numbers. OddOrEven has a cheat sheet that your child can use in the beginning to see which numbers are odd and which numbers are even. This cheat sheet can be hidden once your child is proficient enough to do the test without having to reference back to the cheat sheet. Do as many odd or even quiz questions as you want to. OddOrEven keeps a running score of how many questions has been asked, the number and percentage of the correct answers. OddOrEven also keeps a history list of all the current questions asked, your child's answers and the correct answers so that you can see at the end the questions your child struggles with.
